Web Forms :: Controlling Focus On Form With AutoPostBack TextBoxes?
Oct 29, 2010
I have a form with several textboxes. All of these have AutoPostBack="True".
My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,
If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).
If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.
In other words, I want the form to behave in the way that most users would intuitively expect.
I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?
BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.
Dim CurrentTextBox
As
TextBox =
DirectCast(sender,
TextBox)
If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.
I have 5 textboxes in aspx page, and their AutoPostBack property is True. When I write something to first textbox and press tab key to write something to second textbox, the second textbox don't be focused. I have to select second textbox with mouse to write something it. I want to focus the second textbox by pressing tab key after write something to first textbox. HOW Can I do this?
I have a webform with multiple input textboxes. each box is used in computing somethings, and i am doing these calculations within the TextChanged event for each textbox...this way after the user enters each entry, all calculations requiring that data is performed. I have also set EnableViewState="true" and AutoPostBack="true" cause I am trying to have the textbox keep their data displaying on AutoPostBack. The form is not behaving the way I want it to...right now, if a user inputs data in one field and switches focus to the next, the previous box losses it's data. Is there a way i can get this behaving the right way? I basically just want all the controls to keep their data on AutoPostback.
I have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.
It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.
On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.
Below is my simplified .aspx followed by the codebehind
I have a page that when auto or partial post back happens, focus is set to the address bar rather than the next control. The interesting thing is that when I put an alert in my RadScriptBlock, after the OK is clicked, focus goes to the correct control -or- if I put in an invalid location, focus is returned to the ExpLocation control & when a correct location is input the second time, the tab order/focus command works correctly (see code below).
I am using an asp.net autopostback enabled dropdown list. Here i want to restrict the autopostback property fot the value "Select" in the ddl. I have used javascript for this purpose. but not working.My code look like this.
I have a basic web form with about 5 textboxes. One Textbox is "Date1" and the other is "Date2." Is there a way to set the value of Date1 = Date2 after the user enters a value into the Date1 textbox? I'm using Visual Studion and C#. I'm not much of a programmer, so the less technical the better.
Can i easly edit the defualt registration form and add some textboxes to it and make it as a membership page to subcribe?What if i added 2 types of membership, how can i make the form sends the customer an e-mail and tells him what is his new membership type? how to make a form for customer in his own page after login, allows him to edit his info and make a section in this page tells him some alert .
I've written a small class .That has a method for adding and subtracting.
My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.
I am not sure how to explain my current issue. Right now I have a Form that spans a couple of pages. I have divided the Form into multiple section as well including a File Upload section, a File Download section, and have an 'Update' button at the bottom of the Form. I also have Error labels within each section, and have an Error label at the bottom of the Form under the 'Update' button.The problem that I am experiencing right now is that when I produce one of these errors, the Form automatically displays the very top of the page. So in other words, if the error message is displayed at the bottom of the Form, the user has no idea unless they scroll all the way down.Is there anyway to keep the application focus at the area where the button is clicked on? This way if the user produces an error, they will see it right away.
need to show up 4 columns whenever user press keys in textbox, i need to collect these keys and send it to the service which will give us result as xml. then i convert xml to dataset and binded with datagird. for this i used jquery. after the result displayed ( i mean the result in datagrid which is placed in div), then i need to hide the div when the user clicks outside of the div or press escape key...
function showList() { if(document.getElementById("txt1").value.length > 3) { $("#divList").hide("slow"); $("#divLoading").show(); [code]...
I used Ajax collapsible extenders (1 to 9) with formviews in each of them on a web form.
They are all collapsed by default. If the user enters data in collapsible 5 formview and submits data, the page refreshes back to the top of the page (where the collapsible 1 is positioned). I would like the focus to stay in the region the user is working (even after insert/submit operations). How can I do this.
I have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx
[Code]....
[Code]....
Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.
Is it possible to control a web page from another web page. ?My scenario isI have a page (UI1). It has a hyperlink. Clicking on the same it opens another seperate UI (UI2). UI2 also have a hyper link.My question is , is there any way that I can control UI1 from UI2 using this hyper link
I'm sure you've seen sites that display a portion of the available text in a limited space followed by an ellipsis or a [more] link. That's what I need to do. The text is in a database field, and includes carriage returns and line feeds. I can't just count the number of characters. How can I only display the text that will fit in a defined space? I've tried using a panel control with the height defined. I've also tried a div with the height defined. Neither has worked. How is this done?
I'm new to programming and recently spent some time navigating these forums and searching google to learn how to manipulate Validations with ClientValidationFunction using JavaScript and OnServerValidate with C#. Now that I have a decent handle on it I wanted to give back a bit. I hope some of you all can use this information. Mess around with it and see what its doing and how.I'm using Visual Studio 2008 as my IDE. I did not include a master page so just copy and paste, set break points, and add a watch to the following:
I've done this using bound controls like Repeaters etc but now I need to display information about a single file for example. SO i will pass the fileid in the querystring, then I need to populate some textboxes, autocomplete textboxes etc. and then save changes. what's the most efficient way of doing this?
